The JBX43504 ST/APC to ST/UPC 65-meter simplex fiber patch cable represents a premium solution for professional network installations requiring extended cable runs with minimal signal degradation. Manufactured to exacting standards, this cable delivers the performance, reliability, and compliance certifications demanded by telecommunications professionals and enterprise IT departments. **Advanced Fiber Technology**: Featuring 9/125 singlemode construction with G.657.A1 glass fiber, this cable provides superior signal quality over extended distances. The singlemode design minimizes modal dispersion, making it ideal for long-haul applications where signal integrity is critical. Typical insertion loss of just 0.15dB ensures minimal power loss, while return loss specification of ≥20dB maintains excellent signal reflection characteristics. **Connector Configuration**: The ST/APC to ST/UPC connector pairing offers flexibility for various network topologies and equipment interfaces. Both connector types are industry-standard in telecommunications applications, with APC (Angled Physical Contact) providing superior return loss on the transmitting end and UPC (Ultra Physical Contact) on the receiving end. **Compliance & Certification**: TAA compliant, RoHS/ELV certified, and meeting EU Directive 2002/95/EC, this cable satisfies procurement requirements for government and regulated industry applications. Comprehensive attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards ensures consistent performance across temperature ranges. **Installation & Deployment**: The bright yellow OFNR-rated jacketing provides superior visibility in cable trays and conduit systems, reducing installation errors and simplifying maintenance. The 1.8mm outside diameter allows efficient use of cable management infrastructure. Extended 65-meter length reduces connection points in long-distance runs, improving overall system reliability. **Ideal Applications**: Perfect for data center backbone connectivity, campus network runs, telecommunications infrastructure, broadcast facilities, and any application requiring reliable single-strand fiber transmission. The 90-day limited warranty provides peace of mind, while free standard shipping on orders over $99 offers exceptional value. Custom lengths are available for specialized installation requirements.
